Hello,I've been trying to create a new map of the location of a hill within my city. The problem is that when I save it and then try to export it to Wikipedia Commons, the map is a full area of South America at a scale of 1(cm)= 500 (km). See the f**** map here: http://sharemap.org/public/Cerro_de_las_Tres_Cruces#!flash

I just want the map to be a decent area (my city and its surrounding area). What is the trick?
